GAS-SAVING AT'l'ACl-IIVI ENT.

SPECIFICATION forming part of Letters Patent No. 717,278, dated December 30, 1902.

-' Application ined August 5, 1902.

To @AZZ whom it may con/cern,.-

Be it known that we, PAUL RIEss and CHARLES LANGE,citizens of the United States, and residents of the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Gas-Saving Attachment, of which the following is a full, clear, and exact description.

The purpose of our invention is to provide a device adapted for use in any system of piping, whereby to economize in the use of gas for heating, lighting, and cooking purposes, and to so construct the device that it may be readily and conveniently applied at a burner or at any pointin the system of piping between the meter and the points where the gas is to be consumed.

The invention consistsvin the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out inv the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of. the device shown applied to a burner. Fig. 2 is a horizontal section taken practically on the line 2 2 in Fig. 1, and Fig. 3 is a plan View of the gas-check employed.

A represents a section of a gas-pipe connected with a properly-regulated source of gas-supply, and B an ordinary gas-burner` having the customary barrel-cock C, and D represents the improved device interposed between the service-pipe Aand the burner B.

The body portion of the device consists of an upper single tube 10, threaded to receive the burner or fitted for attachment to a gas-A 12 may be operated-t0 partially or completely sov Serial No. 118,477. (No model.)

tion with the supply-pipe A at one endl and practically abuts the single tube 10 at its opposite end, being connected with said single tube, preferably by means of a union-coupling 14, as is shown in Fig. 1. Within the union-coupling 14 a gas-check 15 is located. This gas-check is convexed on one surface and concaved on the opposite surface, being of dished formation, and is perforated or reticulated, as may be preferred. The mar ginal portion of the gas-check 15 is located between the opposing ends of the inner regulating-tube 11 and the single tube 10 of the body of the device, as is shown in Fig. 1 and the convexed surface of the said gas-check extends into the inner regulating-tube 11, while the concaved surface of the gas-check 'faces the single body-tube 10.

The outer regulating-tube 12 is mounted to turn loosely on the inner regulating-tube 11 and is provided with asuitable handle 16, whereby to readily operate the said outer regulating-tube.

Inthe operation of the device airis admitted in suitable quantities thereto through the openings 13 in the body, and the air and gas mingled therewith supplied to the body is prevented from rushing to the burner or point to ne burned with undue rapidity by the interposition of the aforesaid gas-check 15, which serves to regulate the pressure of gas.

We desire it to be understood that in practice the check 15 may have three, six, nine, twelve, twentyfour, or fifty-six openings to constitute a set of checks which will enable the nserby removing one check and substitutin g another to regulate the pressure of gas as desired. i

Having thus described our invention, we claim as new and desire to secure by Letters Patent A device of the class described, comprising an upper single tube, and two lower regulating-tubes, one of said lower regulating-tubesv `incasin g the other, the said tubes having slots *therein adapted to register whenv the outer tube is rotated relatively to the inner tube, the upper edge of the inner stationary regulating-tube being enlarged and arranged adjacent to the similarly-enlarged lower end of IOO the single tube, a perforated ooncaved gas- I names to this specification in the presence of retarding plate held between the adjoining two subscribing Witnesses.
